PLEASE HELP Part D
In part D of task 1, you identified at least two ways in which the reaction of nitrogen
and hydrogen could be changed to alter the equilibrium. Use the simulation to test
those changes. Describe how you used the simulation to model the changes and the
results they produced. Use these methods if you find them helpful:
• Look at the pie graph to see how the system changes.
• Use the Temperature slider at the bottom to cool or heat the mixture.
. Click the pause button on the simulation to observe the number of particles at
any point of time.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
